This paper investigates on the theorization, design, fabrication and measurement of original
phase shifter (PS) operating with two-step stair phase behavior. The innovative stair PS is …

The miniaturization and application development are the expected challenges on the today
engineering design research on bandpass (BP) type negative group delay (NGD) circuit. To …

We present, in this article, an up-to-date general and brief scan of the main research
activities in RF and microwaves in Latin America. First, we geographically identify the main …

A compact dual-band differential negative group delay (DNGD) circuit with wideband
common mode suppression is proposed. Two small 180° phase shift swap structures of …

This brief introduces a dual transmission structure with bandpass (BP) negative group delay
(NGD) wideband flat behavior. The flat BP-NGD topology is analytically modelled from …

The unfamiliar negative group delay (NGD) circuit is the less familiar function for most of RF
and microwave design engineers. Among the existing types, the bandpass (BP) NGD type …

This brief explains why the coupling between crossed interconnect structure and straight I-
lines of printed circuit board (PCB) presents bandpass (BP) negative group delay (NGD) …

This paper focuses on the time-domain analysis of bandpass (BP) negative group delay
(NGD) function. The innovative NGD investigation is based on the time-domain …

A novel multi‐band pass negative group delay circuit has been designed and proposed. The
circuit consists of three types of components: capacitance, inductance, and resistance. An n …

In this article, a compact distributed septuple-band negative group delay circuit (NGDC) is
proposed and analyzed. It is mainly composed of a high–low–high step-impedance …
